My mom watches tv shows displaying the construction of tiny homes, where the builders have to be creative with the small space they have in the house. They always create very minimalistic expandable, retractable, and even multipurpose furniture. I happened to pass by my mom watching them create an expandable and retractable table, with stools that can function as storage bins. I thought that was really cool and thought about creating one of my own.
As for specifics, I was thinking about making a small couch that can be taken apart and stacked into a table and can also be placed as a bed. I got inspiration from this image:
I’ve never built something on this scale, but I think it could be a fun project and a convenient item for my home.
